Epidemiological data for the included patients.
IQR = interquartile range; SCC = Swiss Concussion Center.
Fig 1.
Comparison between clustering outcomes of the k-means and SOM.
(A) Venn diagram of the overlap between the k-means and the SOM. (B) Overlap between the two clustering methods shown as the percentage of patients from each group identified by the SOM that was identically classified by the k-means. For visualization, the two groups are drawn on the map of layer 5 of the SOM.
Table 2.
Outcomes of the leave-one-variable-out and leave-one-test-out analyses to evaluate the dependency of the SOM on specific inputs.
DVA = dynamic visual acuity; SOT = sensory organization test; V-HIT = video head impulse test; General = sex/age/time since concussive incident/sport type; SVV = subjective visual vertical; VEMPs = cervical and ocular vestibular-evoked myogenic potential; mSPV = maximal speed of the slow phase velocity.
